Not only can you use this to play back streamed HD content from the Slingbox Pro HD on your HDTV, the Slingcatcher acts as a file dump for tons of file formats as well (DivX, XviD). The third and most innovative feature of the Slingcatcher is its ability to take video from your PC (either a portion of a screen or a specific window) and stream that to the Slingcatcher. It lets you watch YouTube video, ABC HD video, or anything you can play back on your computer—but on your living room HDTV.
